San Diego Airport to Tijuana for Surgery: Pickup, Trolley, Border

If you are flying in from elsewhere in the U.S., San Diego International (SAN) is the airport on the American side of the border. It is about 21 miles and 28 minutes from San Ysidro with no traffic (OpenStreetMap routing). For bariatric surgery patients, the transfer may be the clinic's job. One Tijuana hospital's itinerary picks patients up in San Diego before noon and has a driver take them back across to the San Diego airport. Another clinic lists ground transportation from San Diego to Tijuana and back. If your plan does not cover it, this page shows how to get there yourself.

If your clinic sends a driver

1. Ask for the driver's name and vehicle, the exact pickup point at SAN, and what happens if your flight is late.
2. Ask which lane the driver uses to come home. A Ready Lane requires an RFID card for everyone 16 or older in the vehicle (CBP). If you hold only a passport book, the driver may not be able to use that lane with you in the car.
3. Time your return flight with care. One sample itinerary tells patients to plan a departure flight after 2 p.m. on the day they leave. Other clinics may differ, so follow what yours says and leave a cushion for the line.
4. Keep a written copy of what the transfer covers. One package page warns that airfare, extra hotel nights and extra medications may not be included.

If you are getting there on your own

1. Bus to the trolley. MTS Route 992 links the airport terminals with downtown. MTS and SANDAG describe 15-minute service, running from about 4:30 a.m. to 1 a.m. daily after improvements in September 2026 (MTS). It stops at Broadway and Kettner, about a block from Santa Fe Depot (SAN).
2. Or the free shuttle. The San Diego Flyer runs free between the terminals and Old Town Transit Center, where you can reach the trolley (SAN).
3. Blue Line trolley to San Ysidro. The UC San Diego Blue Line ends at the border (MTS). A single ride is $3 since Oct. 1, 2026 (Times of San Diego).
4. Walk across and meet your driver or a ride you booked through an app or stand. The State Department says not to hail taxis on the street (State Department).

This works with a carry-on on the way down. It is a poor plan for the way back after surgery. Book a car for the return.

Why Cross Border Xpress usually does not apply

The CBX bridge connects the U.S. side directly to Tijuana's airport, but CBX says it is exclusive for passengers of that airport (CBX). If you are not flying through Tijuana airport, it is not an option. A passport card also will not help you there: the State Department says you cannot use one to board a plane (State Department).

Documents, in the order you will need them

• At SAN: your normal domestic ID.
• Entering Mexico by land: a passport book or card, and an FMM permit (State Department). Apply online so you do not have to look for an office on arrival with bags in hand.
• Returning: passport, passport card, enhanced license or trusted traveler card (CBP).

If your whole plan depends on your driver's Ready Lane or SENTRI access, get a passport card. It is a useful backup, and it means every traveler in the car qualifies. Our passport guide for Tijuana surgery lays out the options.

Flying home after surgery

This is the question your whole schedule depends on. The CDC says flying after surgery can raise the risk of blood clots, and that delaying air travel for 10 to 14 days after major surgery, particularly surgery involving the chest, will minimize risks from changes in air pressure (CDC). Some bariatric packages send patients home sooner: one sample plan ends on day 4. Those are two different numbers, so ask your surgeon which timeline applies to you and why. Bring up your clot risk directly, since recent surgery, obesity and long periods of sitting all raise it (CDC). Our guide on how long to wait to fly after surgery goes through the procedures.

Sitting in a border line belongs in that same conversation. Ask the driver whether you can walk around during a wait. Ask the clinic what to do if you have pain, fever or vomiting while you are stuck in line, and read crossing the border after surgery.

Who drives after anesthesia

The clinic's driver handles the road, but you still need a responsible adult. The American Society of Anesthesiologists says to have someone with you for at least the first 24 hours after general anesthesia (ASA). One clinic says a companion can come at no extra companion fee, so ask yours the same question.

Prescriptions and post-op supplies

You may leave with several medicines. One clinic's sleeve price covers necessary post-op antibiotics, antacids and pain medication. Before you carry them north, remember that FDA rules make most personal imports illegal (FDA) and that CBP applies those rules at the port (CBP). A separate federal cap applies to controlled drugs (21 CFR 1301.26). Ask your U.S. primary care doctor ahead of time about filling what you need at home. Our medication guide covers the details.

Drawbacks to weigh

• State Department rating: Baja California is Level 3, "Reconsider travel" (State Department). Read Is gastric sleeve in Mexico safe?
• Follow-up after you fly home. Ask who will see you if something goes wrong, and find a local U.S. doctor before you leave. Medicare's coverage outside the U.S. is limited (Medicare.gov).
• Costs not in the quote. Your airfare, return-day hotel and any extra nights are usually yours.
• Taxes. The IRS allows weight-loss costs that treat a diagnosed disease such as obesity (IRS Pub 502). Keep the diagnosis letter with your receipts.
